[0002] Printing is the technology of batch copying the contents of original manuscripts such as text, pictures, photos, anti-counterfeiting, etc. through plate making, inking, pressurization and other processes, so that the ink is transferred to the surface of materials such as paper, textiles, plastics, leather, PVC, PC, etc. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. In addition to selecting appropriate substrates (paper or other printing materials) and inks, the final effect of the printed product still needs to be achieved through appropriate printing methods. There are many types of printing, different methods, and different operations. Multi-color printing uses multiple colors of ink to print patterns on the printing material, and the inks are different in color and cannot be mixed with each other. Only one color pattern can be printed on the surface of the printing material at a time.
[0003] When printing multiple colors, it is easy for the ink of the previous color to be printed before the next color is solidified, causing the colors to mix with each other, resulting in blurred or double images of the printed pattern.
[0004] Therefore, it is particularly important to design a multi-color printing device to solve the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0026] Example:
[0027] The embodiment of the utility model provides a multi-color printing device, which aims to solve the technical problem that in the prior art, when printing multiple colors, the colors are easily mixed together due to the ink not solidifying yet, resulting in blurred or double images of the printed pattern;
[0028] See also Figure 1-Figure 3 , the utility model provides a technical solution:
[0029] A multi-color printing device includes a machine tool 1. Support legs 101 are fixedly connected to both sides of the bottom of the machine tool 1. The support legs 101 provide support for the bottom of the machine tool 1. Rubber pads 1011 are fixedly connected to the bottom of the support legs 101. The rubber pads 1011 enhance the contact stability between the support legs 101 and the ground. A conveyor belt 2 is installed inside the machine tool 1. A rotating motor 201 is installed at one end of the conveyor belt 2 and located on one side of the machine tool 1. The rotating motor 201 drives the conveyor belt 2 to operate.
[0030] Among them, see Figure 1 and Figure 2 A pair of leveling rollers 3 are rotatably connected to one side of the conveyor belt 2 and located inside the machine tool 1. A pressing roller 301 is rotatably connected between the leveling rollers 3 and the leveling plate 4 and located above the conveyor belt 2. The leveling rollers 3 and the pressing rollers 301 assist the leveling plate 4 in pressing and leveling the printing material.
[0031] For further information, see Figure 1 , Figure 2 and Figure 3 A leveling plate 4 is fixedly connected inside and above the machine tool 1. The leveling plate 4 is designed as an arc structure. The leveling plate 4 presses and levels the printing material to prevent the printing material from being too loose or uneven during transportation, which affects the printing effect. An anti-static rubber layer 401 is fixedly connected to the bottom side of the leveling plate 4.
[0032] For further information, see Figure 1 and Figure 2 Three groups of printing processing structures 5 are installed on the top of the machine tool 1 and above the conveyor belt 2. An ink printing box 6 and a drying chamber 7 are installed inside the printing processing structure 5. A feed port 601 is opened on the top of the ink printing box 6. The ink printing box 6 is replenished with ink through the feed port 601. A sealing cover is threadedly connected to the top of the feed port 601. A plurality of anti-skid particles are arranged on the outside of the sealing cover. The sealing cover protects the ink inside the ink printing box 6 to prevent the ink from evaporating and solidifying. A printing roller 602 is rotatably connected to the bottom of the ink printing box 6. The printing roller 602 dips ink to print the printing material. Isolation baffles 603 are fixedly connected to both sides of the printing roller 602 and located at the bottom of the ink printing box 6. The isolation baffles 603 isolate and protect the printing roller 602 at the bottom of the ink printing box 6 to prevent the surface pigment from solidifying and drying due to the warm fan 701.
[0033] For further information, see Figure 1 and Figure 2The drying chamber 7 is located on the left side of the ink printing box 6. Two groups of warm fans 701 are installed on the top of the inner wall of the drying chamber 7. The warm fans 701 dry the ink on the surface of the printing material. Dehumidification windows 702 are opened on both sides of the drying chamber 7. The interior of the dehumidification window 702 is fixedly connected with a dust shield 7021. The dehumidification window 702 discharges the water vapor generated after the ink is dried through the warm fans 701 to prevent the water vapor from affecting the ink drying efficiency. A filter net 703 is fixedly connected below the warm fan 701 and located inside the drying chamber 7. The filter net 703 filters the hot air from the warm fan 701 so that the warm air is evenly blown on the printing material to prevent incomplete drying due to uneven wind force in some areas.
[0034] In addition, it should be added according to the contents of the above embodiments that the rotating motor 201 and the warm fan 701 are both existing technologies, and their internal working principles and operating procedures will not be described in detail here.
[0035] The working process of the utility model is as follows: first, the ink printing box 6 is replenished with ink through the feed port 601, and the sealing cover is tightened to protect the ink inside the ink printing box 6 to prevent the ink from evaporating and solidifying. The printing material is transported to the conveyor belt 2 through the leveling roller 3, and the leveling roller 3 and the pressure roller 301 assist the leveling plate 4 to press and level the printing material. The leveling plate 4 presses and levels the printing material to prevent the printing material from being too loose or uneven during the transportation process, which affects the printing effect. The rotating motor 201 drives the conveyor belt 2 to operate, and the printing material is transported into the printing processing structure 5 through the conveyor belt 2. The printing roller 602 dips the ink to print the printing material, and the isolation baffle 603 presses the printing roller 6 at the bottom of the ink printing box 6. 02 is isolated and protected to prevent the surface pigment from solidifying and drying due to the warm fan 701. The warm fan 701 filters the hot air of the warm fan 701 through the air filter 703, so that the warm air is blown evenly on the printing material to prevent uneven wind force in some areas from causing incomplete drying. The dehumidification window 702 discharges the water vapor generated after the ink is dried through the warm fan 701 to prevent the water vapor from affecting the ink drying efficiency. The whole operation process is simple and convenient. Compared with the existing multi-color printing device, the utility model can dry the ink printing at each stage through design to prevent the colors from mixing due to the ink not drying, and provide pressing and leveling treatment for the printing material during transportation to improve the overall practicality.
